anions, plural;
  1. A negatively charged ion, i.e., one that would be attracted to the anode in electrolysis

  1. a negatively charged ion
  2. (anionic) of or relating to anions
  3. anionic detergent: a class of synthetic detergents in which the molecules do not ionize in aqueous solutions
  4. An ion is an atom or molecule in which the total number of electrons is not equal to the total number of protons, giving it a net positive or negative electrical charge. ...
  5. (Anionic) In chemistry, an anionic species is one that contains a full negative charge. These types of compounds can range in reactivity.
  6. (Anionic) A detergent within which molecules carry a negative charge.
  7. (Anionic) All compounds have an electrical rating for compatibility purposes. Anionic compounds are positive in nature and will blend with like charges or compounds that are nonionic (No charge).
  8. (Anionic) An atom with an excess of elections, resulting in a negative charge. Negative ionic fields are actually benevolent. Waterfalls, moving water (hydro-lines), ocean surfs create anionic fields.
  9. (Anionic) Electro deposition - One of the electro coating (E-coat) methods in which the body is charged positively and the paint negatively. Frequently used OEM primer application.
  10. (Anionic) Forming negatively charged ions in solution. Anionic surfactants include alkylbenzene sulfonates and alcohol sulfates.
  11. (anions) parts of chemical compounds that form negative ions in water (usually non-metals)
  12. An ion with a negative charge.
  13. A negative ion. Alkali, molten carbonate and solid oxide fuel cells are "anion-mobile" cells anions migrate through the electrolyte toward the anode.
  14. A negatively charged ion. Plant nutrient examples include nitrate (NO3^-), phosphate (H2PO4^-), and sulfate (SO4^2-). See cation.
  15. A particle of matter dissolved in water that has a negative charge.  In each system of matter the number of anions is equal to the number of cations (positively charged ions).
  16. An ion with a negative charge, formed when an atom gains electrons in a reaction. The atom now has more electrons than protons.
  17. A negatively charged ion. The most commonly found anions in soil waters include bicarbonates, sulphates, carbonates, chlorides and nitrates.
  18. Neutral atom that gains an electron and becomes negatively charged.
  19. any negative ion (Examples: Cl^-, S^2-)
  20. An ion that is negatively charged and moves toward the positive pole (anode) during electrolysis.
  21. An ion carrying a net negative charge; a compound that has given up a proton thereby becoming electrically charged.
  22. an ion or radical which is attracted to the anode because of the negative charge on the con or radical (as Cl-, OH-).
  23. a negatively charged atom or group of atoms
